Tally control




The MPX detector is desgined to monitor MPX signals and switch one of them to the output.
On an outage of the main input , one of the other sources will be switched to the output.
The MPX signals are switched through relays, so that there is zero influence on the signal.

The detector can be set up and operated via a web interface.

On the front there are 2 switches with indicators that indicate the status.

It is also possible to switch from input 1 to input 2 with the switches.

When switched on, the software in the circuit will start for 8 seconds. This is visible because both switches on the front of the cabinet are lit. After 8 seconds, the main channel switch will remain lit; the other goes out.


The detector also checks the 19Khz signal. Its status can be seen in the web interface. The detector has a network interface for displaying status, configuring configuration and sending alerts. Status notifications occur by means of Emails. The settings for this can be done in the web interface. This interface can be operated via a web browser (Firefox, Google Chrome, etc.).

There is a setting that can also be selected on the front. This is with the switches.

Allows you to choose between MPX1 and MPX2 (the main input) If MPX input 1 has “main” checked as in the example, then the LED of switch MPX1 illuminates. Should input 1 fail and a switch is made to input 2 then the led of input 1 will flash to indicate that there is a fault.


At the back you can find the connections for the MPX inputs and the network connection.

There is also a 9 pin D connector with the text "Tally"

A relay contact is connected to this, which indicates the status of the detector. Pin 1 = NC Pin 2 = NO Pin 6 = common
